Answer:
20.27
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, the sample means with size n of at least 30 can be approximated to a normal distribution with mean and standard deviation 
Using the Central Limit Theorem for Means, what is the standard deviation for the sample mean distribution?
This is s when 
. So
So the correct answer is:
20.27
Answer:
35
Step-by-step explanation:
the pattern is +2 so the answer is 35
QP is the bisector so QPM is half NPM or
Answer:
See below ~
Step-by-step explanation:
<u>Given</u> : 3 angles of a Δ
- (x + 5)°
- (x + 10)°
- (x + 15)°
<u>Solving</u> :
- According to Angle Sum Property of a triangle, the angles of a triangle add up to 180°
- x + 5 + x + 10 + x + 15 = 180
- 3x + 30 = 180
- x + 10 = 60
- x = 50
<u>Finding the angles</u>
- x + 5 = 50 + 5 = 55°
- x + 10 = 50 + 10 = 60°
- x + 15 = 50 + 15 = 65°

Answer:
90° CCW
Step-by-step explanation:
The slope of BA is -1/3. The slope of BA' is 3, so the slopes are opposite reciprocals of one another. These segments are perpendicular, meaning the angle between them is 90°.
Point A' has been rotated 90° CCW about point B.
